Title: Toy
Inventor: RANKIN MARTIN D
IPC: A63H3/02
Filed: 1988-01-12
Granted: 1991-11-12
Abstract: ABSTRACT     A heating means primarily taking the form of  a  soft  toy which  can  transmit  warmth  to a person hugging the soft toy. The soft toy includes a  casing  containing  stuffing material and a heat source within the stuffing material. A heat transfer means  having  higher  thermal  conductivity than the stuffing material extends between the heat source and a portion of the casing  so  as  to  concentrate  heat towards  a  specific region on the exterior surface of the soft  toy.  The  heat  transfer  means  is   of   flexible construction so as to maintain the soft characteristics of the toy.

Title: Coupling device for tubular members
Inventor: SAUER HEINZ
IPC: F16L37/00
Filed: 1988-01-26
Granted: 1991-11-19
Abstract: ABSTRACT           A coupling device between a hose and the radiator of a motor vehicle has a nipple on the radiator with a circumferentially complete rib at its front end.  The front flank of the rib is conical and the rear flank of the rib extends radially of the nipple and is adjacent a groove with three equidistant axially parallel ramps one of which is in line with a bridge extending forwardly of the conical flank.  The end of the hose is attached to a coupling element with three equidistant prongs each having a radially inwardly extending claw at its front end.  The claws slide along the conical flank of the rib when the front end of the coupling element is inserted into the front end of the nipple, and the claws ultimately enter into and are held in the groove.  Each claw has two mutually inclined cam faces, the same as the bridge,  If a claw hits the bridge during attachment of the coupling element to the nipple, the cam faces of the bridge and the cam faces of the abutting claw cooperate to turn the coupling element relative to the nipple so as to ensure that each claw can slide along the conical front flank of the rib on its way into the groove.  The ramps have top lands between pairs of concave surfaces in the groove.  In order to separate the coupling element from the nipple, the coupling element is turned so that the claws slide along the concave surfaces and reach the top lands of the ramps; such top lands are at the level of the radially outermost portion of the rib so that the coupling element can be pulled away from the nipple.

Granted: 1996-07-09
Abstract: The invention in one aspect provides a method of testing drilling mud in use which comprises periodically sampling the circulating mud and analyzing its aqueous filtrate at the rig site by ion chromatography for selected positive and negative ions; one or more other parameters of the sampled mud and/or mud filtrate (eg pH, temperature) may also be measured; preferably the composition of the mud filtrate thus monitored in interpreted to indicate downhole interactions, with the composition of the mud supplied to the hole being adjusted to or towards the optimum as drilling proceeds.  The invention also provides a method in which the solids of the periodically sampled mud are analysed at the rig site, eg for sorbed ions and/or for cation exchange capacity; the values so obtained are preferably combined with those for the mud filtrate analysis and used in the diagnosis of downhole conditions for adjustment of the composition of freshly supplied mud.  The invention further provides a method of analysing drilled shale solids in drilling mud in use which comprises drying and separating these solids from the mud, extracting ions from the separated solids into solution, and analysing the resulting solution by ion chromatography for selected positive and negative ions; these operations are conducted at the rig site, and the resultant data, usually along with analyses of the circulating mud composition, are preferably used to indicate appropriate adjustment of the composition of the mud supply to or towards the optimum as drilling proceeds.

Title: Byte write error code method and apparatus
Inventor: SMELSER DONALD W
IPC: G06F11/10
Filed: 1988-05-13
Granted: 1991-05-14
Abstract: ABSTRACT OF THE INVENTION           A method and apparatus for error detection is disclosed.  A data word and its check bits are read from memory, and new check bits are generated from the data word read.  A logical operation is performed between the new check bits and the check bits read from memory to generate a syndrome.  The syndrome is decoded to detect the presence or absence of an uncorrectable error.  If an uncorrectable error is detected, a logical operation is performed between the new check bits and a byte write error code to generate a third set of check bits, which are then written into memory along with the data word.

Title: Group-control for elevators
Inventor: SCHRODER JORIS
IPC: B66B1/20
Filed: 1988-07-25
Granted: 1991-08-27
Abstract: A B S T R A C T          This group-control provides immediate allocation of floor-calls to elevator cars and better allocation decisions, and future overloads are more accurately determined.          Misallocations are therefore avoided and the average waiting time for all passengers is reduced.  For the purpose of determining the most favourable car, a computer in each elevator calculates, from the distance between a floor and the car-position indicated by a selector, from the intermediate stops to be expected within this distance, and the car-load, a total proportional to the time lost by waiting passengers.  By means of call-recording devices, arranged at the floors, in the form of 10-button panels, calls for target-floors can be fed-in.          After the calls have been stored, load-values contained in a load-table are altered in such a manner that they are increased at the input-floor in proportion to the number of calls fed-in, and are reduced at the target-floors in proportion to the number of calls for the relevant target-floor.  The load-values thus determined are taken into account in calculating the total, a monitoring circuit preventing the allocation of calls which would cause overloads.

Abstract: Enhanced hiding power for opacifiers in paints, inks, and other coatings is provided by employing the opacifiers, such as TiO2, ZnO, talc, CaCo3, and the like, adhered to or embedded in the surface of thermoplastic microspheres.  The composite opacifier-microsphere material is readily formed with  a  preselected specific  gravity,  so  that  there  is little tendency for the material to separate.  In addition, the composite behaves in the coating as a opacifier-air interface,  having  a very high difference  in  refractive indices, and exceptional hiding power.  The high volume to weight  ratio  of  the  composite affords  very  attractive economic  advantages,   effectively  reducing  the  weight proportion of opacifiers required in the formulations, and other related advantages.
